TO ALL WHOM IT MAY CONCERN: A

Be it known that 1,',HENRY McGANN, of Cleveland, inthe county of Cuyahoga, and {State'of Ohio, have" invented certain new and usefulA Improvements in Water-Regulator for Steam-Boilersgand I do -hereby declare that the following is a full and complete description of the same, reference being had tothe accompanying drawings, making a part of this specification, in which- I i Figure 1 is a front view of the apparatus,

Figure 2 a side View, i I Figure 3 a vertical section, Figure 4 detached sections. Likeletters of reference refer to like parts in the several views. y In fig. 1, A `represents the case or shell in which the pendulum B swings from the shaft C, iig. 4, said shaft being projected through the side of the case, and in which it has its bearings@ Y To the lower end of the pendulum is attached a iioat, D, the purpose oi which will hereinafter be shown; i To the outer end of the shaft C is keyed an arm, E, the lower end of which forms the segment of a circl, from which proceed cogs, which are made to engageinxthe cog-wheel F. Said wheel is keyed tothe plug G, g. 4t, of the water-cock H, fig. 2, and by which it is turned, as follows: f y Y Y 1. The apparatus is fixed to the head ofthe boiler, or at any other appropriatejplaee,and atsuch apoint in i relation to the water, that the pendulum will hang vertically. as shownin iig. 3,"when the watelgfis at the lowest point of safety. i f y I v l i The shell `or case is put in communication with the boiler by pipes leading lfrom the sanie,'and connected to the case at the ends H', into which they are' screwed. i Y Y i, i

By this it will be obvious that thewater will ilow from the boiler into the shell,v and that it will always be at-the same height in the case as it is in the boiler, as a direct and free communication is'establish'ed between them. i i j Y l As the water is raised in the boiler tothe highest water-line, so also will the watchin the casebe raised to the same point, the result of which will be to carry or float upward the ball D, butuvhicli, in consequence of being attached to a straight, rigid pendulum, will, as it iioats upward, carry the pendulum` to one side, as indicated by the dotted lines a. I

.Y The pendulum, as above said, being connected 4to the shaft C, will cause thestem or plug of the 4cock to`. turn, which will give to 'the segmental arm E a vibratory movement, which, actuating the wheel F, will cause itV to turn, and with it the'plug of the cock, thereby stopping it, shutting off the 'inilowing water from theboiler at the highest water-line. Now, as the water may descend in the boiler, so also `will itvdescendin tli'eshell, and as it recedes from the highest water-line toward the lowest, the float will fall, `andgth-e1eby open the cock'and allow the water before stopped out to ilow into the boiler, and thusv prevent its descent below the liie of safety. As the boiler begins again to iill by the in'flowing of the water, the oat will also rise, operating the cock, and entirely shutting the same when the water rises to the highest water-line. i

By this self-acting regulator the water in the boiler can never fall below the lowest water-line; hence all danger of a collapse and explosion arising from a deficiency of water can never take place,.as the boiler is con` stantly keptv supplied to its required height. 4 l i What I claim as my improvement, aind desireto secure by Letters Patent, is i The arrangement of the pendulum B, shaft C, case A, segmental arm E, wheel I, and cock H, substau tially as herein specified.
